Electrical connector for multiconductor flat insulated cable This invention relates to an electrical connector for a multiconductor flat insulated cable, and, more particularly, to an insulation-piercing connector which allows formation of an electrical connection between the conductors of a multiconductor flat insulated cable and the terminals of the connector where the center spacings of the terminals are greater than the center spacings of the conductors.
Multiconductor flat insulated cable is used throughout the electronics industry for ease of termination, space requirements and economy. Ordinarily, the conductors of such a cable are disposed in coplanar sideby-side relation with center spacings of 0.05 inches (1.27 mm). An almost endless variety of connectors have been developed for use with such cable in practically every application in the industry.
However, in certain segments of the industry, for example, in military installations, series "D" subminiature connectors are preferred. A series "D" connector ordinarily comprises a male plug and a female receptacle having a plurality of contacts, i.e., terminals, arrayed in at least two staggered parallel rows in which the center-line spacings of the terminals in each row are 0. 109 inches (2.74 mm), the rows of terminals being staggered, i.e.., offset, 0.0545 inches (1.37 mm) and located 0. 112 inches (2.81 mm) apart. With center spacings of 0.0545 inches (1.37 mm), series "D" connectors cannot be used with standard multiconductor flat cable. The difference in center spacings between the conductors of the cable and the terminals of the connector (0.05 in. vs. 0.0545 in.) would preclude using the two components in the same system.
One method which has been suggested for solving this compatability problem is with specially adapted cable in which the center spacing of the conductors alternates between 0.05 inches and 0.0545 inches. One need only select the section of cable which has the desired center spacing for the available connector prior to making a termination.
Another method which has been suggested for solving the compatability problem is by redesigning a pierce-type connector to include elongated flexible terminals which can adapt by bending to the desired center spacing. Such a connector is the "Amplimite" High Density Flexible 20 Connector from Amp, Inc., Harrisburg, PA. Since the terminals are elongated, one may encounter increased electrical resistance with this connector system.
There has yet to be suggested a simple and economical connector adaptation whereby a series "D" type of connector may be used with standard multicanductor flat insulated cable without redesigning the cable and/or the connector system. The term "standard" as used herein means a multiconductor cable in which the conductors are spaced 0.05 in. (1.27 mm) apart.
According to one aspect of the invention, there is provided an electrical connector for an insulated flat cable having a plurality of insu- lated conductors disposed in coplanar side-byside relation comprising a base of insulating material, a pair of opposed walls integrally joined to said base, the opposed surfaces thereof being disposed at the same angle relative to the transverse axis of said base, a plurality of terminals arrayed in staggered parallel rows between the opposed walls, each of said terminals comprising an elongate pin mounted in said base and extending perpen- dicularly therethrough in parallel spaced relation to one another, a pair of insulationpiercing tines integrally joined to one end of said pin, said tines being in parallel spaced relation to each other, disposed in a common plane and defining a slot therebetween, and said common planes being angularly orientated at a predetermined angle relative to the transverse axis of said base.
According to another aspect of the inven- tion, there is provided a method of forming an electrical connection between the conductors of a multiconductor flat insulated cable and the terminals of a connector, said terminals being generally vertical relative to said con- nector and arrayed in staggered parallel rows, each terminal having a pair of insulationpiercing tines in parallel spaced relation to each other disposed in a common plane and defining a slot therebetween, said slots having a center spacing greater than said conductors, comprising the steps of angularly orientating the planes of said tines at a predetermined angle relative to the transverse axis of said connector so that the center spacings of said slots coincide with the center spacings of said conductors, moving said cable normally toward said slots at said predetermined angle, forcing the ends of each pair of tines to perforate the insulation on each side of the conductor aligned therewith and expose the portion of the conductor between the tines free of insulation, and forming an electrical connection between the tines and the exposed portion of the conductor.
According to a further aspect of the invention, there is provided a series -D- type electrical connector (as defined herein) having a base and a plurality of bifurcated terminals mounted in said base and arrayed in stag- gered parallel rows, wherein each row of said terminals is orientated at a predetermined angle relative to the transverse axis of said base.
